Application led September 14, 1915. Serial No. 50,628.

To all 'whom it may concern:

Be it known that I, HOWARD W. Foss, a citizen of the United States, and a resident of lrving, county of Essex, and State of New Jersey, have invented a certain new and useful Improvement in Window-Cleaning Devices, of which the following is a full, clear, and exact specication.

lThis invention relates more particularly to a class of devices adapted to be used for cleaning purposes.

My invention has for its object primarily to provide a device designed to be utilized in al manner whereby window panes and the like may be easily cleaned from the inside thereof instead of requiring the person doing the work to risk the danger of being injured by leaning out of the window, and which is of an adjustable as well as being of an extensible form so that windows, tran-` soms, etc., located at various heights may be conveniently cleaned. The invention consists essentially of a supporting member, or bar having in one of its ends a threaded passage which is substantially T-shaped to provide a vertically disposed branch transversely therethrough as well as a communieating branch, or recess in the end of the bar, and the second end of the supporting bar is slotted in a manner to provide two spaced yielding prongs o n one of which are a number of teeth, or stops extending into the slot. Adapted to be removably mounted in one of the branches of the T-shaped passage of the supporting bar is a rod soas to be disposed in various directions relatively to the supporting bar, and adj ustably mounted on this rod is a bracket having a toothed member to permit a cloth, or wiper to be detachably applied thereon.

Other objects of the invention are to provide in the slot of the supporting bar an adjustable handle, or rod having teeth, or stops cooperating with the teeth of the supporting bar for limiting the movement of the handle when in an adjustedposition; to provide means' for holding the teeth of the adjustable handle and the teeth of the supporting bar in releasable engagement; and to provide a window cleaning device of simple, emcient and durable form.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views,

the said invention being more fully described hereinafter, and then pointed out in the claims at the end of the description.

.ln the drawing, Figure 1 lis a sectional view, partly in detail, taken vertically through a window, showing one way of using my device for cleaning the panes thereof.

Fig. 2V is a detail sectional View taken on the line Il ll of Fig. 3.

Fig. 3 is a view of one end of the device.

Y Fig. l is a view, partly in section, taken on the line V-lV of Fig. 3, and

Fig. 5 is a front view of the bracket used in the device for holding a wiper.

rlhe window cleaning device has a supporting member, or bar which may be of any suitable length, and shape, though this bar is preferably substantially square, as viewed transversely. rlhrough one end of the supporting bar 10 is a threaded passage 11 of approximately a T-shape to provide a vertically disposed branch, as 12, and a communicating longitudinally disposed branch, or recess 13 when the supporting bar is positioned ina longitudinal direction. In the second end of the supporting bar 10, and also disposed vertically therethrough, is a slot ll whichis of a length so as to extend approximately to the center of the bar to provide two spaced prongs 15 and 16, the bar being made of material so that these prongs will yield sutliciently for being sprungoutwardly from each other. Projecting inwardly of the slot 14 from the free end part of the prong 16 are a number of ratchet-shaped teeth, or stops 17, and transversely through the prongs midway of the teeth is a threaded opening 18.

Adapted to be removably mounted on the supporting 'bar 10 is a rod 19 which may be of any desired length, and one end of this bar is threaded, at 20, so as to be detachably screwed into the threaded T' shaped passage 1l of the supporting bar. When it is desired to dispose the rod 19 upwardly at a right angle with relation to the supporting bar, as shown in the drawing, the threaded end of the rod is screwed in the upper end o-f the vertical branch 12 of the passage, and when it is desired to dispose the rod downwardly at a right angle with respect to the bar the threaded end of the rod is screwed in the lower end of the vertical passage, or when it is desired to dispose this rod longitudinally with relation cia to the bar the threaded end of the rod is screwed into the recess 13 of the supporting bar, as illustrated in dotted lines Fig.

ln order to permit a wiper for cleaning the glass of a window to be carried on the adjustable rod 19, a bracket, as 21, is provided. rlhe bracket 21 has a sleeve 22 adapted to be moved to various positions on the rod, and projecting laterally from this sleeve is an arm 23 having on its outer end a toothed member, as 2a. The toothed member 24@ as well as the arm 23 may be integrally formed ot wire to provide the me1nber with spaced portions on its upper and lower edges. somewhat in the itashion of teeth, or this member may be made in the form of a plate having toothed upper` and lower edges, or other means may be used in conjunction with the bracket so that a cloth, or any suitable pad, as 25, for cleaning glass may be removably applied thereto. "lhrough the sleeve 22 ot the bracket 21 is a hreaded orifice 26 in which is passed a set screw 2T adapted to be rotatably guided into and out of engagement with the rod 19 lortightly holding the bracket against accidental movement when adjustedon the rod.

To allow the supporting bar 10 with the rod 19 and the wiper 25 to be conveniently guided for cleaning the outside or the glass ot a window so that the person manipulating the device may accomplish the work from the inside of the window, l provide an adjustable handle, or rod 28. rlhe handle 2S may be of any desired length, and one end ot' the handle is formed with a ilat head 29 having a. threaded opening 30 centrally therethrough. The head of the handle 2S is movably disposed in the slot 14 of the supporting bar 10 so that its threaded opening 30 is in register with the threaded openings 18 through the prongs 15 and 16 of the supporting bar, and projecting from one Jface oi' the flat head of this handle are ratchetshaped teeth, or stops 31 of a similar number to the ratchet-teeth of the. prong 1G of the supporting bar. The teeth of the handle 28 are reversely shaped to the teeth ot the prong 1G of the supporting bar so that one set of the teeth will mesh with the other set, and serving as means to hold these sets of teeth in releasable locked engagement, through the registered threaded openings of the prongs or' the supporting bar as well as through the opening of the head of the handle 8O is guided a set screw 32. lWhen the set screw 32 is rotated accordingly the yielding prongs 15 and 1G or the supporting bar 10 will be forced against the spring action of these prongs Jfor clamping the teeth of the handle and the prong 16 together. rllhe handle will thereby be held against movement.y and when the set screw is reversely rotated the spring action of the prongs will cause them to be sprung apart for allowing the handle to be adjusted to a desired position relatively to the supporting bar 10.

To use'the device for cleaning, 'for instance the outside of the glass of a window, as illustrated in F ig. 1 at 33, the lower sash 3st is raised some distance, and the upper sash 35 may be lowered if desired. rlChe handle 28 is then suitably adjusted with respect to the supporting bar 10, as above described, and the rod 19 is screwed in the upper end of the vertical branch 12 of the T-shaped passage 11 of the supporting bar so that the rod will extend upwardly. The bracket 21 with the wiper applied thereto are adjusted on the rod 10 for the wiper to be guided in contact with the glass, following the disposal of the supporting bar and the rod through the window under its raised lower sash. By then guiding the handle 28 in directions to move the supporting bar and the rod so that the wiper will pass in contact with various parts ot' the surface of the glass the window pane will be easily cleaned without requiring the operator of the device to lean out of the window. Moreover, by adjusting the rod 19 and the handle 28 in various positions on the supporting bar, as hereinbefore explained, windows located at unusual heights may be readily cleaned by the use ot my device.

In the foregoing description, I have embodied the preferred forni of my invention, but l do not wish to be understood as limiting myself thereto, as I am aware that modiications may be made therein without departing from the principle, or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, l claim as new and desire to secure by Letters Patent 1. In a window cleaning device, a supporting bar, a rod carried by said bar and removably held by one end thereof, said bar having means by which said rod may be held in various directions relatively to the bar, a bracket slidably mounted on said rod, a wiper detachably connected to said bracket, and a handle on the other end of said bar; said handle being adapted to be angularly adjusted with respect to said bar, together with means for locking said handle to said bar whereby it will be held in adjusted relation.
